• Patients with certain forms of cataract or corneal disease have diminished visual acuity in a brightly lit environment. This is due to increased light scattering, which causes increased glare sensitivity. In a series of experiments, a sequence of bottles containing a suspension of latex particles was used to simulate the effect of different degrees of cataract and corneal edema on visual acuity. It was shown that anodized honeycombs could substantially improve visual acuity through the latex-containing bottles. The mechanism of visual improvement was shown to be by reduction of glare and increase in contrast.
